--- Comment #1 from Mark Johnston <markj@FreeBSD.org> ---
The problem is that your code is not calling jailparam_import() or
jailparam_get() (with some JID specified in the parameters). In this case,
there is no value to export, i.e., jd_value == NULL and we trigger a null
pointer dereference. But, the library should probably check for this case and
return an error instead of crashing.
